Jointly with a team around Professor Dirk Sliwka, University of Cologne, and Prof. Patrick Kampkötter, University of Tübingen, and on behalf of the Institute for Labour Market Research (IAB), this project develops the fourth wave of the Linked Personnel Panel (LPP), a linked employer-employee panel data-set for personnel economic research.Within the project we analyze the relationship between firm performance, individual job quality and Human Resource Management (HRM). Especially the change processes over time within the HRM dimensions “recruiting and personnel planning”, “human resource development”, “performance management and compensation”, “commitment, values and firm culture” and “diversity and demography” are in the focus of the project.
